Ok, I recorded another demo with some general visual suggestions, then put it up on the beta server and recorded some game play since a bunch of people were on.
My first thought after playing it with other people: WAAAAY too many grenades. Seems like there are two grenades for every person on the team. Another complaint I heard was that the sky was too low. Not many people took the low path, so it was a pretty easy (though slower) flag capture if you did take it. Spawn angles definitely need to be fixed. The beginning of each round was often disorienting.
Edit: Oh, and one more thing. The sides of the jail are better now, but in the middle, all the players basically look black. Not such a big deal since teams don't matter there, but it would be nice to have more light in the center.
